Abstract: Technology for switching from a wireless local area network (WLAN) to a wireless wide area network (WWAN) is disclosed. A multi-radio access technology (multi-RAT) user equipment (UE) can receive WLAN-specific dedicated physical random access channel (PRACH) allocation information from an evolved node B (eNB) to enable the multi-RAT UE to perform an inter-RAT WLAN-to-WWAN handover. The multi-RAT UE can initiate the inter-RAT WLAN-to-WWAN handover at the multi-RAT UE by performing random access with the eNB using the WLAN-specific dedicated PRACH allocation information.

Abstract translation: 公开了从无线局域网（WLAN）切换到无线广域网（WWAN）的技术。 多无线电接入技术（multi-RAT）用户设备（UE）可以从演进节点B（eNB）接收特定于WLAN的专用物理随机接入信道（PRACH）分配信息，以使多RAT UE能够执行 -RAT WLAN到WWAN切换。 多RAT UE可以通过使用WLAN特定的专用PRACH分配信息与eNB进行随机接入，来在多RAT UE处发起跨RAT WLAN到WWAN切换。
